To all whomfzt waag/,doneerm Be it known that I, ROBERT E. EINSTEIN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Railway-Frogs, of which the following is a'full, clear", and exact description, such as will enable others skilled in the artto which it appertains to make and use the saine, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan View of a railway frog embodying the features of my invention, one of the guard members being in section; Fig. 2 is a cross sectional view taken' on the line 2-2 of Fig. 1; Fig. 3 is a cross sectional view structures,` and particularly to railway frogs having a. guard member attached to or combined with the frogl proper for guiding the wlieeliiange past the point(of the frog by means of a tread rim contact in a horizontal plane above the top surface of the frog.

The main object of my invention is to cheapen the 'construction and increase the efficiency of this class of fiogs. v

i Another object is to provide a guard member which can be used with the railway frogs that are in general use and also be capable of being applied to said frogs after they have been installed.

Another object of my invention is to provide a guard member which is so constructed that by changing the position of saine after it has become worn the engaging face of saine will be brought closei to the running line of the frog and thus compensate for wear, thereby enabling said member to be used for an extended period.

Another object of my invention is to provide a guard member of regular shape and form which after becoming worn at one end 'can be intere-hanged with the guard member at the opposite side of the frog with whichjt is used or av different frog of the same angle and thus bring into commission the opposite end of the guard member which has been subjected to very little wear, And still .another object of my invention is to provide means for preventing .the frog or 'the rolling stock from receiving a sudden shock as the wheel .enters the frog,l this being accomplished by -so constructing the guard member that the tread rim of the wheel engages the same' gradually.

Referring to Fig. 1 of the drawings which represent the preferred form of Amy invention, 1 designates 'the point of the frog, 2 and struction. lArranged adjacent the rails 2 and 3 are guard members 5 and 6 which extend above the tread faces of the heads of said rails, as shown in Fig. 2said guard members extending over the headsfof said wing rails for a ortion of their length adjacent the point ofp the frog, as shown in Fig. 1, so that the rim of the-tread of the-car wheel 7 will engage the vertical faceofgthe head of said guard member, thereby gui the wheel ange past the point of the frog. Said guard members each consist of a central straight portion and flared end portionsE which extend at an angle to said central porwith relation to the frog that one of the ared end ortions of each guard member extends para lel to the adjacent face of the point of the frog. The central portion ofthe guard same by fillers 8. The guard members are preferably held by bolts 9 passing through them and through the fillers and rails which rmembers can be retained by means of clamps or by attaching said members to plates placed under the frog. i ff In Fig. 1 I have shown the guard member as consisting of a casting provided withsuitj If desired, I can use a casting of suitable form l provided with an engaging' face of relativelyT l harder material than the other members of l the frog.

When in operative positon the head of one! ofthe flared ends of each guard member profjects over the, head of its co-o erati'ng wing rail and the base of said guar member proconstitute the frog but if desired, the guard 3 the wing rails of the frog, and 4 a filler, the l parts above referred to being of ordinary condmgvs tion,- the guard members being so arranged 8oA members diverge slightly from thev wing rails 2 andl 3 and are held spaced away romg able strengthening ribs, said casting coin ris .ing a head 10, a web, and a base 1l.v I dejelcts over the base of the rail, thereby aiding in'securing the wing rails to the cross ties. The guard members may be securedto the cross ties by spikes which engage the bases thereof, as shown at the lower portion of Fig. 1, or, if desired, laterally projecting eXtensions 1,6 can be formed integral with the base vv`of the guide member and be provided with .JobA

' of regular form and both ends are of the same openings to receive the Jfastening spikes as s own at the upper portion of Fig. 1.

t The openings 'in the web of'the guard member through which the retaining bolts Q pass "are similarly located at both ends of the uard member and are formed equi-distant lrom each other, and as the guard member is guide member becomes worn, the bolts can be removed and said member adjusted toward the toe 18 of the frog to bring the engaging face of said member closer to the running line of the frog and thus compensate for As previously stated7 the central portion of the guard members diverge'from the.wing rails so that the wheel, in passing from the toe toward the point ofthe frog, will begradually forced to its clearing position of the point and thus prevent the guard member t and frogfrom receiving a sudden strain or shock.`

Having thus: described my invention, what I claim as new and desire tofsecure by Letters -Patent is:

1. A railway frog comprising a frog point, wing rails, and guard members comprising `Webs projecting upwardly from bases and having portions which extend over the heads of the rails adjacent the point of the e frogfsubstantially as described..

5o E and baseswhich resten-the heads and bases 2. A railway frog comprising a frog point, Wing rails, and guard members having heads ofifthe .wing rails adjacent, the point of the frog,.ai`1d means for securing said guard menil .bers position; substantially as described. l lY 35A railway frog comprising a frog point,

wing rails, and guard members of uniform shape and size adapted to be interehanged with each other, and each consisting of a base, web and ahead which extends over the head ot the wing rail with which it co-operates; substantially as described.

4. A railw ay frog comprising a frog point, wing rails, and guard members each of which has a central straight portion, and liared ends, one end of each guard member extending parallel with one face oiC the frog point, and-spacing blocks interposed .between the guard members and the wing rails at the toe end of the frog; substantially as described.

5. A railway frog, comprising frog point, wing rails,and guard members which are so constructed thatthey can be moved longitudinally of the frog when their engaging faces have become worn to bring said enga ing `faces closer to the running lines of the frog and thus compensate for wear; sub stantially as described.

6.,' A railway i'rog comprising a frog point,

wing rails, and guard members of uniform sha e in cross section throughout their length an each consistingl of a straight portion which is spaced away from the wing rails, and a flared portion which rests on the head oi the wing rail adjacent the point of the frog; substantially as described.

7. As an article of manufacture, a guard ing having a web provided at its upper end with a head which. is adapted to project slightly over the head of one of the wing rails of the frog, and a base which is adapted to rest on the base of said wing rail; substantially as described.

8. As an articleol manufacture, a guard member for a railway fro consisting of. a casting having a web provided at its upper end with a head which is adapted to project slightly over the head of one of the wing rails of the frog', said casting having laterally pro jecting extensions provided with openings 'member for a railway frog comprising a cast- IOC to receive fastening devices; substantially as described.

ln. testimony whereof, .l hereunto affix my signature, in the presence of two witnesses, this thirdday .of August, 1906.
